Moog Prototype The First Moog Synthesizer

This Moog synthesizer is one of two prototypes built by Robert Moog from July-September 1964, with additional modules added in 1964 and 1965. One was taken to Toronto University in 1965, while this one was kept by the inventor and his colleague, Herbert Deutsch. It was used in live public performance for the first time in a concert at Town Hall in New York City on September 25, 1965.
